I'm interested in adding the 755 to my current system. I'm using the Arcam AVR 100 as my surround preamp/processor. I use B&W 601s and matching center, surround and sub. Are the gains matching? Do I need to worry? Will the 755 add much ooomph? I just moved into a bigger space and want the extra loudness both for home theater and music (EAD transport/DAC).

Any info is great...
